efficient means for controlling the raising ofthe earth-turning elementsthereof, and it consists 1n the combinations and constructions Indescribing ,this invention, reference is a had to the accompanyingdrawings, in which like characters designate parts in all the views.

Figure 1 is a side elevation, partly broken away, of a plow embodying myinvention. Fig. 2 is a detail view of a portion of the means for raisingone of the earth-turning elements. Fig. 3 is a view similar to Fig. 2,showing the parts in their positions occupied when the earth-turningelement is raised. Fig. 4 is a detail of the crank axle looking to theright in Fig. 2, part of the frame being also shown.

My invention is here illustrated as embodied in a reversible hillsidesulky plow having two earth-turning elements, or plows proper, arrangedto turn respectively right and left furrows, said elements being shiftable into and out of the ground independently of each other. However,this inventilon may be. embodied in any type of sulky p ow.

.1 is the frame of the plow; 2 are ground or supporting wheels arrangedon opposite corresponding sides of the frame; 3 are earth-turningelements, or plows proper, the beams of which are pivotall y connectedrespectively to crank axles upon which the ground wheels are looselymounted, these axles being also pivotally connected to the frame.

As best seen in Fig. 4, each crank axle is formed at its'outer end witha spindle 4 carrying one of the ground wheels, and is journaled at itsopposite or inner end on a spindle 5 fixed in a bearing 6 associatedwith the frame 1. Each axle is also formed with crank portions 7, 8extending laterally from the spindles 4t, 5 and connected by a cross arm9 which is journalcd in a suitable bearing 10 (Fig- 1) fixed to the beam11 of one of the plows or earth turning elements. Moreover, each axle isalso formed with, a

crank portion 12 extending parallel to the crank portion 8 and clampedor otherwise secured to the crank portion 7 of such axle, the crankportion 12 being journaled at its free end on a spindle 13, which isfixed in a bearing 14 associated with the frame 1, and axially alinedwith the bearing 6 of the frame, the spindles 5 and 13 and the crankportions 8 and 12 forming a pivotal connec: tion betweenthe frame 1 andthe axle provided with such crank portions. The axles form no part ofthis invention, and any other suitable axles may be substitutedtherefor. Y

The means for raising the earth-turning elements out of the ground andcontrolling the. shifting thereof into the ground are alike inconstruction and a description of one of such means is sufficient. Saidmeans includes a clutch member for connecting one ground wheel with thecorresponding axle,

' and a cam movably mounted on the frame,

the" clutch member being normally out of connection with the groundwheel and the cam operating to move the clutch member into connectionwith such ground wheel.

As here shown, the clutch member comprises a sliding pawl 15, Fig. 2,carried by, and slidable lengthwise of, a movable part, as a lever 16mounted on the spindle a and having a bearing 17 between its ends whichreceives the spindle 13 for the crank .portion 12 of the correspondingaxle. The clutch member-15 cotiperateswith a ratchet wheel 18 rigid withthe ground wheel 2 on the spindle 4 and is normally lield'out ofengagement with the ratchet wheel 18 by a spring 19.' Said clutch member15 is movable into engagement with the ratchet Wheel 18 by a cam 20pivoted at 21, Figs. 2 and 3, to the frame 1 and having a surface 22eecentric with its pivot 21, said surface coacting with the advance endof one arm of a power-transmitting part, as a lever 23 which is pivotedintermediate of its ends at 24 to a lug 25 on the lever 16, the otherarm of the lever 23 being connected to the clutch member 15 by apm-and-slot, the pin 26 of which extends transversely through a slot 27in the lever 16 and into the clutch member 15. The cam 20 is alsoformedwith a cutaway portion at 28 at the end of the surface 22 forpermitting the advance end of the lever 23 to be depressed after saidlever 28 has traveled over the surface 22 and. the earth-turning elementhas been raised to a predetermined height.

The cam is moved on its pivot21 by a suitable arm or element 29, fixedthereto,

- and is returned by gravity to its normal position. As here shown, thecam 20 1S l1m1ted,

in its pivotal movement by the bearing 17 of the lever 16, which bearingprojects into an opening 30 provided in the cam 20 and is en gaged byopposite sides of such opening. The lever 16 moves along a sector 31fixed to the frame 1. and arranged concentric withthe axis of thespindle 13, the sector being provided with rack teeth 32 on its .underside which codperat'e with a pawl 33 on the clutch, member 15, thispawlc33 holding the earth-turning elementin its raised position.

When the clutch member 15 is moved into engagement with the ratchetwheel 18, said pawl 33 is moved out of engagement with the rack 32. Theclutch member 15 is also formed with a laterally-extending lug orshoulder 34 which engages the upper face I 35 of the sector 31, saidface being arranged levers, one of which, as 37, is connected by a link38 to the clutch member 15 as by a pinand-slot 39, the lever 37operating to depress the clutch member 15 sufliciently to move the pawl33 out of engagement with the rack 32 but not sufficiently to shift theclutch member 15 .into engagement with the ratchetwheel 18, in orderthat the plow may be shifted by hand. The other of the levers, as 40,carried by the lever 16, is also'connected to the clutch member 15 inorder to move the pawl 33, the lever 37 being more convenient to operatewhen the parts are in the positions shown in Fig.2, and the lever 40being more convenient to operate when the parts are in their positionsshown in Fig. 3. The spring 19 which holds the clutch member 15 in itsino erative position, encircles the link 38 and i interposed between alug 41 on the lever 16 and a shoulder 12 associated with the. link.

In operation, when 1t is desired to raise the earth-turnin element outof thc'soil, the foot engaging the element or arm 29 is depressed movingthe eccentric surface 22 of the cam 20 into engagement with, andslidably along, the power-transmitting lever 23- and operating saidlever to depress the clutch member 15 into engagement with thegroundwheel thereon, and 'efi'ect' by the travel-0f the sulky the partsare shifted until they occupy the positions seen in'Fig. 3.

parts, rides or slides on the eccentric surface 22 of the cam 20 andholds the clutch mem- 18 until the advance end of said lever .20,whereupon the clutch member 15 will be withdrawn by the spring 19 out ofengagement with the ratchet wheel '18, or in case the spring 19 is notstrongenough to withdraw the clutch member 15 the shoulder gagement withthe ratchet wheel 18.. For slightly raising the earth-turning element,the lever 37 may be operated and for permitting the earthturning elementto be delever 40 may be operated. Thelever 40 may also be used forforcing the clutch member 15 into engagement with the ratchet wheelelement during the travel of the sulliy.
